Abstract
For architectural survey, the most important factor is to create a very believable drawing of the existing building, structure or monument (sculpture). In order to carry out such surveys, there can be used reflectorless tacheometers, phototheodolites, digital cameras and surface laser scanners. Nowadays, it is the most expeditious method of obtaining the detailed and reliable information concerning the particular object. With the help of laser scanning, it is possible to create the most accurate and detailed digital models of the whole environment in the shortest possible time. The information concerning the object in the form of a point cloud can be got in minutes. Thus, we have a unique opportunity for real-time monitoring of the processes, both natural and manmade character.
